Great review!! Thank you.. I did see another Vevor punch review that did put an oval p&d in, and it worked well. They simply clocked it while setting up and before locking the die in place. I kind of like the idea of that as you can set the slot in any direction. Thanks again!!
I built a set of crimping dies for 3/8 Aluminum duplex cable sleeves like those used for Awning and Winch cables. Customer had the same punch as your new one. Clocking was handled in the tooling and I swapped the supplied setscrew in the lower die pocket for one with a Dog point. Those punches are a great power source for lot's of crimping and forming applications with a little creative tooling design.
Structural bolting requirement is the hole is 1/16" over diameter of the bolt. This is rounded to 2mm in metric. Your die set is about 1.2mm over shank size. It looks like the "bolt size" is labeled in imperial and the actual punched hole size is in metric for your dies.
Its an interesting option, I use a mag drill quite often for various plates I need to weld. Mag drills are versatile but sometimes it can be a lot of set-up when you have to drill a pre cut plate. I have to use an off cut if an I beam to stick to and then clamp the smaller plate to the I-beam. I can see this being a more efficient option for much of that.
seems it would be a minimal change to make it index the dies so you could punch square holes as there is ton of need for carriage bolt holes in sheet steel.
I currently have a W.A. Whitney 70-ton punch that I use here at work. I have used it to punch oval and square holes even though it has no means of clocking the punch or die. If you align the set before you punch and are careful not to rotate the work while punching it is possible to use any punch and die set. But "careful is the keyword here.
Great review - Thanks! I've had this CH-70 for a few months and it has not failed me at all, cutting 3/16 and 1/4 plate with the half inch round mainly. My only regret is that I couldn't find a more powerful pump (electric -- way to large and expensive) for speed, so use that 10000 psi air jobbie like you. By the way, this unit does do the slotted punches as several are offered for this machine, BUT as you noted, you gotta get that alignment correct from the get go -- by running dry with the die held up onto the punch, then activating slowly, and then tighten in position ... carefully. The ram seems not to rotate, so it's okay. I do not know why, but the slotted punch and die sets are insanely expensive right now (early 2023).
Yes, not a bad idea at all, as long as you do not have to create a large number of the slots (extra material removal could get a bit labor intensive, depending on material thickness). @@332ARA
Cool i needed the pipe thread info, im on larger too, cheers stsyed for the whole video. I got air pump for mine from vevor too, unbelievably cheap for what time it saves you over drilling. Cheers
That's a healthy unit there Stan. Looks like it outta give you years of service. I was surprised at the price too. Keep on punchin' Bubba!! Regards, Duck
Great review, Stan. good experience? They are really quick to ship for me - usually next day or two. It is really amazing what one of these punches can do.
To bad you cant torture test the unit. I picked up a scrapped forklift tine today that someone dragged around till the tips were a 1/16" thick. Be entertaining to see how it would do going up in thickness up the taper. Going to end up cutting it up to hopefully forge into hammers once I finish building my coal forge.
Surprised they sent you that and not the electric one they sell like you hougen 🤷♀️🙈. I bought one of the smaller 6 ton hole punches mostly for the dies for my gabro manual punch 🤷♀️ was cheaper to buy thier whole 6 ton unit than I could find individual dies for 🙈🤷♀️. It works great but tiny throat . So the dies get used more in my gabro
For a few hundred dollars more you might be able to buy a 30-ton or heavier punch press at a machinery auction. Machinery is selling for dirt cheap right now, particularly in California, thanks to the poor business climate and all the regulations created by the democrats. A punch press has a much deeper throat, is much, much faster, has a bigger shut height and greater adjustability, plus you can build and or buy all kinds of tooling for it. IMO it would be way more flexible and usable. The downside would be the space required and perhaps getting it into your workshop. Just my opinion.
I'm sure you could,but it would be a pain in the arse to move it to the job site every time you need it, unlike this unit that was designed for portable punching

Nice review....sure beats drilling. Impressive looking frame on that thing ! Man what a bummer losing the Hougen 😢😢
Thanks Stan !
Looks to be a good tool, Stan, but not nearly as convenient on the job site as the Hougen.
Cool. Maybe you can make some star-shaped dies for the holiday season.
Great review - Thanks!

Could one do overlapping round holes?

This is why I write the model/serial number and date of purchase on my manuals. That way I can report them stolen when they walk off the jobsite.
good spell check the one we used was a lot bigger and was a hand full to move as it was heavy and you could punch RSJ with an angle web

nice punch. the packaging is lacking. I think if they used spray foam to fill the box so it can't flop around would help keep it all together
Great review, Stan. good experience? They are really quick to ship for me - usually next day or two. It is really amazing what one of these punches can do.
2 days, got here pretty quick. But the warehouse is right here in Cucamonga.
Dang, I was hoping it would be faster...I'm looking for something I can show my boss so we can upgrade from out manual hole punch.
Looks nice and heavy duty
Wouldn't this punch be more useful if you could get more punch sizes? I need 1/8" and maybe 3/16" .

Need some punches with a shear angle to them then you can go larger sizes.
I can’t imagine you’re actually bleeding any air out of the system on a single line system like that when it’s uphill to the tool.
Well, I did cycle it several times with the power unit above the punch when I first hooked it up. I figured that was sufficient.
We used a tool just like that But was marooned in 1976
Cool piece of kit!
Did you determine how the floor plate (3:50) is used? Looks like a really nice tool.
Believe that peice is used for small parts when the punch is retracting from the piece being punched
Sorry, I didn't mention it, that is for thinner materials to aid in retracting the punch (stripping)
Personally I don't have the use for it but still, it's a nice toy.
Well, if you’re going to make your own punches & dies, you’d need to heat treat them & harden it… I wonder where you could get a good oven for that? 🤔
Bought this and it runs extremely slow, have taken it apart and everything checks out, any ideas?
Assuming you got all the air out of it, the speed of the punch is dependent on your pump volume.
Good review Stan
I bought Amazon slot dies for this. cost 18 each size
Sr plz one time triyeal
Me haces el favor d darme el costo d esta punsonadora

can i ask what pump you are using?
It's a TEMCO air over hydraulic, get your pump with the highest flowrate you can.
I was looking at getting a set of Drill Hog left hand drills to replace the single drill I recently accidentally mangled. Good stuff ?
Drill Hog is highly recommended, you break them, they get replaced.
Can you power one of these punches with a porta power jack?
If it makes 10K pressure, sure.
Thanks for sharing
Cool
Pretty slow alrite

Point well taken😉.
Wow, really ? I thought all the guys selling factory equipment were from the rust belt.
